This CL changes the way dart: libraries are considered supported when used in conditional imports or bool.fromEnvironment constant using the "dart.library.*" values. Library nodes now has an isUnsupported flag which is set according to the "supported" property in the libraries specification. Furthermore the Target now supplies a DartLibrarySupport interface that allows targets to override whether dart: libraries are unsupported. This allows the JIT/AOT to use the same platform file but still consider dart:mirrors unsupported in AOT mode, and dart2js to consider the internal library `dart:_dart2js_runtime_metrics` supported. Furthermore, the internal handling is changed so that condition imports and bool.fromEnvironments constants are computed through the same logic for "dart.library.*" values, avoiding the need for passing these values through the environment.

Dart
A client-optimized language for fast apps on any platform
Dart is:
-
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
-
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
-
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
-
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
-
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
